Abstract: Before the year 2000, The historic meteorological observation data were often recorded on papery meteorological documents which are important foundation for meteorological researches but are complex-formatted and dif ficult to deal with.Recent years, especially since the end of 1970’s, Many great efforts have been made to Rescuing and digitizing the papery historic meteorological archives as the rapid modernization of meteorological data management and data sharing service. The total amount of digitizing data is steadily increasing. More than 80, 000, 000 pages of meteorological observation data digitizing graphics have been scanned in color so far. The Guidelines on Meteorological data rescue (QX/T-201-2013) has been established.Some preliminary explorations of online digitizing graphic data sharing have been gradually proceeded. The digitizing technology have been briefly descripted including the standard File formats designing, color scanning, manually paper digitizing, color records curve tracing and data processing, digitizing data integrating and quality controlling. Also the rescued achievements of meteorological data, especially the long time series of meteorological data that derived from digitizing have been served. These datasets have been extensively used in analysis of climate change and many other science researches.
